Research

  My previous works

You can find my previous works here,


[1] Water Film Motor

Fluid Film Motor : A soap film carrying electric current rotates under applying extrnal electric field (See here)


[2]Rotation of Polar Liquid Films

Rotation of polar liquids: Polar liquids rotate under applying extrnal electric current and field



[3]Instability and Rotation of Liquid Crystal Films

Instability in Liquid Crystals : Three rotating vortices on the film of liquid crystal convert to a rotation (See here).


[4]Elecrto/magnetically induced rotation

Fluid bulk motor : Rotation of water volume carrying an electric current when magnetic field is applied (See here).




My current works



 [5] Rotation of Water bulk

About this phenomenon


[6] AC Rotation

About this phenomenon     

Direct flow with AC field: Applying high frequency nonuniform electric field produces regular flow in soap film (more).


 

[7] Rotation and in Asymmetric Frame

About this phenomenon 

Our observation show that producing rotation in fluid film with using an electric current (in absent of the external electric field)in assymetric frame (see here).


[8] Vibration of Fluid Film

About this phenomenon

If the passed electric current through the fluid film to be the alternating while the applied external electric fiel is direct, the film will vibrate (See here).


[9] Spreading a Droplet by a Soap Film

About this phenomenon

Spreading of a droplet : A water droplet is spreaded on a soap film and produces a new film (more and more).

 

 I would be glad to do Science with evryone who interested in these works.





Open questions:

 



Foam Rotation
 : Each bubble of a foam rotates separatly when an electric field and current are appied on the foam.


Instability in Liquids : Irregular motions of suspended mesetylene film because of passing electric current.


 

Nematohydrodynamics: Suspended MBBA liquid crystal film between two polorades (See here).


Rotation of metalic fluid : Rotation of a Mercury droplet under applying magnetic field and electric current.


Ferrofluids : Repels on a ferrofluid suspended film (more).







Our Model

 

 We have presented a simple theoritical model that explains some above experiments (Please see here).
